Greetings Jeffreyc1235,
We see that you have questions related to HomeKit notifications for your accessories and we're happy to assist.
To begin, have you configured a home hub as described at Set up your HomePod, HomePod mini, Apple TV, or iPad as a home hub? If so, have you also configured the notifications as reviewed at Get notifications for your HomeKit accessories and ensured that your notification settings aren't preventing those from displaying as expected?
If those articles don't help, providing additional details on the steps you've taken and any specifics related to what you're seeing may help increase the chances of a helpful reply to your post.
Cheers!
